STM6717/6718/6719/6720 STM6777/6778/6779/6780
Dual/triple ultra-low voltage supervisors with push-button reset (with delay option)
Features
- Primary supply (VCC1) monitor. Fixed (factory-programmed) reset thresholds: 4.63 V to 1.58 V
- Secondary supply (VCC2) monitor (STM6717/18/19/20/77/78)
- Fixed (factory-programmed) reset thresholds: 3.08 V to 0.79 V
- Tertiary supply monitor (using externally adjustable RSTIN): 0.626 V internal reference
- RST outputs (push-pull or open drain); state guaranteed if VCC1 or VCC2 ≥ 0.8 V
- Reset delay time (trec) on power-up: 13.2 ms, 210 ms, 900 ms (typ)
- Manual reset input (MR)
- Optional delayed manual reset input (MRC) with external capacitor (STM6777/78/79/80)
- Low supply current
- 11 µA (typ), VCC1 = VCC2 = 3.6 V
- Operating temperature:
- 40 °C to 85 °C (industrial grade)
